The mitsu pumps are costly, you wont sell the farm but might need a morgage.
My mitsu has 2 pumps, the second being driven from the front crank pulley using the pulley to PTO Mitsu adaptor and a u-joint.
That might be something to consider as an alternative.
I did this for faster loader operation as the factory unit was real slow, factory unit now serves only for the 3-point lift.
Fortunately my loader incorporated a reservoir in one of the frame posts and it resulted in much less footage of hoses hanging around to get damaged.
If any are available, there are a couple of members that generally will chime in as they specialize in Mitsu parts.
